_FILE_STANDARD_INFORMATION_EX structure

Description

The FILE_STANDARD_INFORMATION_EX structure is used as an argument to routines that query or set file information.

Members

`AllocationSize`

The file allocation size in bytes. Usually, this value is a multiple of the sector or cluster size of the underlying physical device.

`EndOfFile`

The end of file location as a byte offset.

`NumberOfLinks`

The number of hard links to the file.

`DeletePending`

The delete pending status. TRUE indicates that a file deletion has been requested.

`Directory`

The file directory status. TRUE indicates the file object represents a directory.

`AlternateStream`

The alternate data stream status. TRUE indicates the file object represents an alternate data stream.

`MetadataAttribute`

The metadata attribute status. TRUE indicates the file object represents a metadata attribute.

Remarks

EndOfFile specifies the byte offset to the end of the file. Because this value is zero-based, it actually refers to the first free byte in the file; that is, it is the offset to the byte immediately following the last valid byte in the file.
